  • World Tuberculosis Day aims to create awareness about the disease that affects millions of people each year
  • The theme for 2018 World Tuberculosis Day is Wanted: Leaders for a TB-free World
  • TB is the leading cause of death related to antimicrobial resistance and the major killer of people with HIV

World Tuberculosis (TB) Day is observed on 24th March to raise awareness about the disease and to take efforts to end the global TB epidemic. TB is the world's leading infectious killer, responsible for 1.7 million deaths per year. This year's World Tuberculosis Day commemorates the 136th anniversary of Dr. Robert Koch's announcement in 1882 of his discovery of the TB-causing bacteria. Despite significant efforts, TB continues to claim over 4,500 lives a day. Multidrug-resistant TB (MDR-TB) poses a major health threat and could have an impact on the efforts taken in the fight against TB.
World Tuberculosis Day - Wanted: Leaders for a TB-free World

The theme for 2018 World Tuberculosis Day is "Wanted: Leaders for a TB-free world." The theme focuses on building a commitment to end TB by involving all the leaders in the fight against TB.

Wanted: Leaders for a TB-free World

The theme for the World Tuberculosis (TB) Day encourages leaders not only at the political level with the Heads and Ministers, but at all levels from Mayors, Governors, parliamentarians, community leaders, doctors, nurses, health workers and also people with TB to join hands and take efforts to end TB.

TB is deeply rooted in populations where human rights and dignity are limited. Tough TB can affect anyone, the disease thrives among people living in poverty and communities that are marginalized and other vulnerable populations. Some factors like malnutrition, poor sanitation, use of tobacco and alcohol and diabetes can affect vulnerability to TB and access to care.

What is Tuberculosis?

Tuberculosis an air-borne infection caused by bacteria called Mycobacterium tuberculosis (M.tuberculosis). TB can be transmitted from one person to another through the air.

Latent TB is a condition in which a person is infected with the TB bacteria, but does not have an active TB disease and cannot spread TB to others. Nearly one-third of the world's population has latent TB.

People with a poor immune system, such as those living with HIV, malnutrition, and those who use tobacco have a higher risk of falling ill with TB. TB affects the lungs, causing a bad cough that lasts longer than two weeks. Some of the symptoms of TB include a chronic cough with blood, fatigue, fever, loss of appetite, malaise, night sweats, loss of muscle, unintentional weight loss, shortness of breath and swollen lymph nodes.

TB can be diagnosed with a chest x-ray, skin test, sputum microscopy, culture test and Genexpert test. TB can be treated, and most of the drugs for TB were developed many years ago. A combination of TB drugs should be taken at least for a period of six months. Some drugs have severe side effects, and there is an urgent need for new TB drugs to be developed. With the emergence of MDR-TB, many people are now resistant to one or more of the drugs. Drug susceptibility testing can help identify the drugs a person is resistant to.

The first key step to eliminate TB is prevention. The prevention of TB is to stop the transmission of TB-causing bacteria from one person to another. People affected with TB should receive effective treatment for the disease to prevent the transmission.
